The height of the cylinder is 22 inches.

What is height ?

Height, altitude, and elevation all refer to the vertical distance between something's top and bottom or its base and something above it. Height is used to describe everything that may be measured vertically, high or low.

Height is a measurement of vertical distance, or how high something or someone is (how tall they are) (how "high" a point is). For instance, "That building is 50 meters high," or "An airplane flies around 10,000 meters high."

Height is a basic physical characteristic that is commonly expressed in feet (ft) plus inches (in) in the United States and centimeters (cm) in other countries. The SI unit would be meters since these are length measurements. Remember that x feet plus y inches is typically written as x' y.

Seeing the figure we get to know the measures of cylinder

The 3 types of 3-dimensional coordinate systems are the x-axis, the y-axis, and the z-axis.

The Cartesian coordinates of a point in three dimensions are a triplet of numbers (x,y,z). The three numbers, or coordinates, specify the signed distance from the origin along the x,y, and z-axes, respectively.

The three axes intersect at the point called the origin. The x-axis is the horizontal line along which the wall to your left and the floor intersect.

The y-axis is the horizontal line along which the wall to your right and the floor intersect. The z-axis is the vertical line along which the walls intersect.

To locate the point (a, b, c), we can start at the origin O and move units along the x-axis, then b units parallel to the y-axis, and then c units parallel to the z-axis.

At h(2) = 4 the value of 'I' will be equal to 0.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the function is h(2) = I + 4. The value of I at h(2) = 4 will be calculated as,

h(2) = I + 4.

4 = I + 4

The three types of coordinate input in AutoCAD are absolute coordinates, relative coordinates, and polar coordinates

Absolute coordinates are based on the origin of the drawing, which is the point 0,0. To specify an absolute coordinate, you enter the X and Y coordinates of the desired point. For example, if you want to specify a point at X=4 and Y=6, you would enter ‘4,6’.

Relative coordinates are based on a point relative to the last point specified. To specify a relative coordinate, you enter the distance in the X and Y directions from the last point specified. For example, if you want to specify a point that is 4 units to the right and 6 units up from the last point, you would enter ‘4,6’.

Polar coordinates are based on a distance and an angle from the last specified point. To specify a polar coordinate, you enter the distance and angle from the last point. For example, if you want to specify a point that is 8 units away at an angle of 90 degrees, you would enter ‘8<90’.

No, a triangle with sides 25 cm, 5 cm and 24 cm does not make a right triangle as these lengths does not adhere to the Pythagorean theorem.

A right triangle has one angle that measures exactly 90 degrees. In a triangle, the longest side (the hypotenuse) is opposite the right angle.

The Pythagorean theorem states that in a right triangle, the sum of the squares of the two shorter sides (legs) is equal to the square of the hypotenuse.

In this case, the side lengths do not satisfy the Pythagorean theorem, as (24^2 + 5^2 = 601) ≠ (25^2 = 625)

The polynomial function in standard form that has the zeros - 2 (multiplicity 2), and 3+i (multiplicity 1) is option b: f(x) = x^4-10x^3+38x^2-64x+40.

What is a polynomial function?

In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable.

The zeros of the polynomial function are -

2 (multiplicity 2), and 3+i (multiplicity 1)

If the zero is 2, the factor is (x-2).

A multiplicity of 2 implies there are 2 factors -

(x-2) or (x-2)(x-2) = (x-2)^2

= (x^2-4x+4)

For the complex zero (3+i), there will also be a zero at the complex conjugate (3-i).

The factors are -

= [x-(3+i)] and [x-(3-i)] or

= (x-3-i)(x-3+i)

= x^2-3x+ix-3x+9-3i-ix-+3i-i^2

= x^2-6x+9-i

= x^2-6x+9-(-1)

= x^2-6x+10

Multiply all factors to find the polynomial in standard form -

f(x) =  (x^2-4x+4)(x^2-6x+10)

= x^4-6x^3+10x^2-4x^3+24x^2-40x+4x^2-24x+40

= x^4-10x^3+38x^2-64x+40

Therefore, the polynomial function in standard form is x^4-10x^3+38x^2-64x+40.

Finding the center of dilation of two lines involves determining the point that is equidistant from the two lines.

A dilation is a transformation that changes the size of an object, but not its shape, and the center of dilation is the point from which the object is scaled.

The center of dilation of two lines can be found by constructing a line perpendicular to both lines that bisects the angle between them. The point of intersection of this line with the segment connecting the two closest points on the two lines is the center of dilation.

To find the center of dilation, we can use the following steps:

1. Draw the two lines and find the angle between them.

2. Draw a line perpendicular to both lines and bisecting the angle between them.

3. Draw the segment that connects the two closest points on the two lines.

4. The intersection of the line from step 2 with the segment from step 3 is the center of dilation.

It's also possible to use vector and linear algebra to find the center of dilation for two lines. By finding the slope of each line and their intersection point, the center of dilation can be found as the midpoint of the intersection point of the two lines.

In conclusion, finding the center of dilation of two lines requires determining the point that is equidistant from the two lines.

It can be done by drawing a line perpendicular to both lines that bisects the angle between them, or by using vector and linear algebra to find the intersection point of the two lines and finding the midpoint of that point.

Solve:

8(x-10)=-88

Using the distributive property.

How to use distributive property:

Multiply the outside number by the inside parenthesis numbers.

Like this;

8x - 80 = -88

Now add 80 to both sides:

8x - 80+80 = -88+80

8x = -8

Divide both sides by 8:

x = -1

If each of the quadrilateral is a trapezoid, then the measure of ∠Q = 89 and ∠S = 153.

A polygon with only one set of parallel sides is called a trapezoid. The parallel bases of a trapezoid are another name for these parallel sides. Trapezoids have two additional sides that are not parallel and are referred to as their legs.

Given that in a trapezoid, the angle T is 91 and the angle R is 27.

For a trapezoid the measure of angle are as follows:

∠T + ∠Q = 180

∠R + ∠S = 180

Substituting the measures of ∠T and ∠R in the above equations we have:

Step-by-step explanation:

the point-slope form is

y - y1 = m(x - x1)

m is the slope, (x1, y1) is the given point.

so,

y - -1 = 2(x - 6)

y + 1 = 2(x - 6)

An equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation is y = -4x - 32.

Mathematically, the point-slope form of a line is given by this mathematical expression:

y - y₁ = m(x - x₁)

Where:

From the given linear equation y = -4x + 2, the slope is given by:

y = -4x + 2

m₁ = -4

In Geometry, two (2) lines are parallel under the following conditions:

m₁ = m₂ (m represents the slope.)

At point (-6, -8), an equation of this line can be calculated in slope-intercept form as follows:

y - y₁ = m(x - x₁)

y - (-8) = -4(x - (-6))

y + 8 = -4(x + 6)

y + 8 = -4x - 24

y = -4x - 24 - 8
